Instructional Ideas

• Form collaborative groups with similar levels of pupils and allow time to work with the lower groups
• Have learners create a list of the algebraic properties and include an example for each

Classroom Considerations

• Expects an understanding of algebraic properties

Pros

• Encourages class members to provide two methods of simplifying the same expression
• Uses collaborative methods to practice which one encourages communication

Cons

• None
